To all whom it may concern:

a new and useful Pneumatic-Tire-Shoe-Manufacturin Machine, of whichthefollowing My invention manufacture from flat sheets of rubbercoatedcanvas of the open-bellied casings or more briefly the open casings ortire shoeswhich are used in connection with an inflatable inner rubbertube to constitute the double-tube pneumatic tires now used onautomobiles and the like. Heretofore such open-bellied or opentire-shoes in so far as they have been fabric have is the subject ofthis application. It is the first machine, known to me, which has comeinto. commercial use for this pur ose of building tire-shoes fromsuperpos weaving woven or ring-core orformer.

My machine comprises a power-driven;

By this means I am, enabled to supply a round ofcanvas onthe ringcore from one roll and then a second round of canvas onthe ring-core from the other roll. lBy properly arranging the rolls withrespect crossed, as is necessary in building strong tires. The pair ofstock-rollers may be mounted one above the other, or side by side v on asliding or rotary table so that the stock power driven can readily" bedrawntherefrom 'to the ring-core ingmachine of a power-driven ring-corewith a pairjof stock-rolls from which alter-j nate layers of crossedfabric may be supthe ring-core,

riphery to shape the sides of the tire.- These spinning-rolls arepreferably springpressed and their outer periphery or working edge isdisk-shaped and rounded so as not to cut the fabric. The spinning-rollsare also radially movable with reference-to the rimcore. They have beenfound peculiarly e cient in shaping the sides of the tire-shoe and forman important feature armamention. They are sharply diflerentiated fromthe hammers or sliding finger devicesheretofore proposed'for thepurpose. So, too,

the combination of the tread-forming roll for operating upon the treadortion and the spring-pressed spinning-r01 s for shaping the sides ofthe tire-shoe by radial mo tion with reference to the rin core forms anefiective instrumentality for completely shaping the tire and animportant feature of my invention, 1 I

the stock-roll.

It is important to secure roper tension on the fabric as this is drawnrom the stockroll onto the ring-core. To this end I cause the fabric topass over a rubber-covered roll to which someform of tension brake isapplied. '1 have found, also, that the fabric under tension from thestock-roll These I remove by a stretching-roll supplied a pair ofdivergent spirals on its surace. Without unduly 'extendingthispreliminary outline of my invention, 1 may say thatan important feature:of my machine of the muslin which is unwrapped To this end I apply as:another feature of my invention atake-up roll for the muslin which isdriven by fric-v tional contact against the outer surface of 45different stages of application; Fig. '13 is a operate upon thering-core while this is moving at a much higher speed, say at twohundred and seven turns a minute. By this means the machine not onlydoes more work in a given time but it does better work. I

I shall now describe, in detail, the ma chine which constitutes the bestembodiment 'of my invention now known to me.

. Referring to the drawings in detail, 1 is the base carrying acylindrically-formed member 3 u on which loosely turns the rotary head 8ymeans of a ball-bearing connection 5; The base 8 is provided with aseries of pairs of lugs 13, the space between each pair forming a recessto receive a lockf member 14 mounted on the side of the cy inder 3 forarresting at predetermined intervals the movement of the head. Extendingupwardly from the head 8, as seen in Fig. 1, are two varieties ofstandards 15, 16. The f ur standards are L shaped in; cross-section andare positioned with the anbest in Fig. 10, from the outer end of whichprojects, a stub shaft 25 provided with a spring catch 26 for holding astock-roller 27 on which the sup ly of rubber-saturated.

fabric 28 is woun the successive layers of which are prevented fromsticking together by interposing between them. astrip of muslin or cloth29. By releasing the catch 26, the roller 27 may be removed from itsshaft 25 and replaced by another roller on which a fresh supply offabric and cloth is wound whenever the supply on the original rollerbecomes exhausted.

Mounted on the shelf17 (Figs. 1 and 2), which extends horizontallyacross the upper corner or angle of the standards 15, is an uprighthanger 18 having a laterally extending arm 19 to the free end of whichis pivotally mounteda depending yoke 20 and having mounted on pins inits free ends thereof a roller 23, hereinafter designated as the take-uproller. Below the arm 24 is an idle roller 30 (see Fig. 2) mountedbetween the standards 15 and 16.

In the front or outer portion of the standards 15, 16 are bearings toreceive a shaft on which is mounted a tension 'roller 36, preferablyhaving its outer face covered with a layer of vulcanized rubber 361,which rubber-coating I have found peculiarly efiicient. The tension-rollconstitutes a highly important element since it secures the ap-' roller36 (Figs. 2 and 7) a disk 42 around which is a friction band 43 havingone end anchored to a post 44 on one of the standards and having itsother end connected to a rod 45 bearing a tension measuringg'a'ge 46 anda turnbuckle 47 at its lower end. The turnbuckle 47 is connected withsome fixed support such as the base 8 by means of a second rod 48. Ifincreased tension is desired .on the tension-roller 36 the turnbuckle 47is manipulated so as to cause a contraction of the friction band 43 onthe disk 42 to a determined degree, indicated by the gage 46 so that apredetermined amount of resistance will be offered to the turning ormovement of the tension-roller 36.

I have found that as the ring-core draws the fabric under tension fromthe stockdinal creases which must be gotten rid of.

The expedient which I have finally hit upon for this purpose consistsof'a stretching-roll 41, here shown as mounted in a swinging frame 40.The outerv surface of the stretching roller 41 is provided with twospirally arranged sets of grooves both commencing at the longitudinalcentral line thereof and diverging spirally therefrom to cause it tolaterally stretch and smooth the rubber-saturated fabric which is drawnpartly around it in its passage from the tension-roller, the effect ofthe roller being to. remove all longitudinal creases and other wrinkleswhich will be formed in the fabric during the removal of the stock fromthe stock-roller on its passage to the ring-core. The arms are permittedto swing on bolts and are held in any determined position by tighteningnuts. By passing the fabric over the tension-roll and under thestretching-roll, the fabric is in contact with the surfaces of theserolls for a considerable fraction of the circumference.

It will be understood that the stock-roll the idle roll, thetension-roll and the stretching-roll constitute a single set of rolls,there being, in the'case shown,-four sets or two pairs of sets of rollsin all, one pair of set of rolls cotiperating withone ring-core and theother pair of set of rolls cotiperating with the other ringcore.Considering the pair of stock-rolls which cotiperate with a singlering-core, it is understood that the rubber-coatedcanvas is ap lied tothe two stock-rolls at alternate anges which means that when the stockrolls cotiperate with the ring-core the threads of the fabric from oneroll will be at an angle with the direction of the threads of the fabricfrom the other roll. This is brought about, in the construction whichhas just been described, by mounting a pair of set of stock-rolls uponthe rotary head 8-. But the same result could be obtained among numerousother ways by mounting a pair of stock-rolls upon a sliding head, asshown in Fig. 13, or by mounting the sto .k-rolls' one above the other,as shown in Fig. 14 and placing the stock upon the pairs of stock-rollsso that their threads will come at angles to each other when supplied tothe ring-core. V

The operation of a set of rolls is as follows: In order that thering-core may take hold of the fabric, the core is coated with Therubber-coated canvas is now unwound from the stock-roll and carrieddownwardly under the idle roll 30,

and from thence upwardly around the tension-roll 36, and from thencedownwardly under and around the stretching-roll 41, and finally onto thepower-driven ring-core to which the end of the canvas-is made to adhere.Since the ring-core is power-driven surface of the tension-roll. Tnthismanner the fabric will be smoothed by the stretchround of canvas hasbeen applied to the ring-core, the length is cut off by the workmansscissors from the'portion remaining on the stock-rolls} The cloth whichis interposed between the layers of the rubber-coated canvas on thestock-roll asses downwardly around the under face of the stock-roll and'frome thence upwardly and is then rewound on the take-up roll 23 which,being hung between the arms .of the pivoted yoke 20, frictionally restson the surface of the stockroll 27, thusreceiving motion thereby. Duringthe operation of withdrawing the strip of rubber-coated canvas from thestockroll, the lug 14 (Fig. 2) will be inserted in the recess betweenthe lugs 13 to prevent the revolution of the head 8.

l[ have now to describe the source of power for the ring-core. Mountedon the base 1 is a motor 49 having a sprocket wheel 50 driving asprocket chain 51, passing around a sprocket wheel 52, on a shaft 53,supported by brackets-54. The shaft 53 bears, at its ends, sprocketwheels 55 driving sprocket chains 56, passing around the loose membersof clutches 57 which with their cooperating tight, members 59 aremounted von shafts 58 (Figs. 3, 4, 5) and are operated by clutch levers59. Mounted on suitable ways 69 at each end of the base lare, housings61. Each of these housings maybe progrooves so as to render them movableon the ways 60 and is held ina determinedrpoof Which engage in slots 63formed in the base 1. The housing 61 is hollow and is provided with anopening through which the shaft 58 enters (Fig. 4). 'Within thehousing-a're a pair of with bearings bolted to the walls .of the housingand supporting one end of the shaft 58. Extending longitudinally of thehousing 61 and supported in bearings suitably secured to inturnedfiange's'69 formed integral with the body of the housing is a shaft nearthe longitudinal center of which is' splined a clutch member 71 havingits two lateral faces formed to engagecorresponding clutch members 72and .73 mounted loosely on said shaft 70. Thecl'utch member 7 2 isprovided with a hub 74 rigidly secured to a spiral gear -7 5 adapted tobe drlven by means of a worm- 7 6 mounted on the shaft 58 just as thecorresponding clutch member 73 has a hub 84 .secured to a spiral pinion83 driven by a worm 82' on a shaft 78. The

fshaft 78 is driven from the shaft 58 by a at a low speed, therubber-coated canvas will.

vided on its under surface with suitable alined brackets provided bedrawn outwardly from under the surface of the stretching-roll as well asover the-"1' ing-roll and the'proper tension will be applied to it bythe tension-roll. When onesition by means of bolts 62, the lower endschain and sprocket connection and the arrangement is such that thespiral gear 88 rotates much more rapidly than the spiral gear 75. Itwill thus be seen that the shafts 58 and 78 are constantly power drivenand rotating. With them rotate the clutch-members 72 and 73,which areloose on the shaft 70. By throwing the clutch member 71, which issplined on the shaft 70, into connection with either the clutch member73 or 72, the shaft 70 is made to revolve slowly or rapidly. Themovement of the clutch member 71 is effected by the shifting lever 86.

Mounted on the shaft 70 outside of the housing 61 is a gear 88 (Fig. 5)adapted to mesh with a pinion 89 secured to the ex tended end of a shaft90, mounted in the up per partof the housing 61 and carrying alocking-disk 93. Cooperating therewith is a spring pressed locking pin100 held out of engagement with the locking-disk by a cross pin 97moving in a slot in the casing 95 (Fig. To look the shaft 90 in a fixedposition, the pin 100 is allowed to assume the position shown in Fig. 3.To permit the shaft 90 to rotate, the pin 100 is withdrawn from contactwith the locking-disk 93 and held in this withdrawn position by thecross pin 97 which bears against the end of the casing 95, all in amanner readily understood. l

I have now to describe the chuck for carrying the ring-core. Mounted onthe shaft 90 is a chuck (see Fig. 11) comprising a cup-shaped bodyportion 101-provided with an internally threaded hub 102 to receive theend of the shaft 90. The interior of the member 101 is further providedwith a flange 103 provided with openings 10st in radial alinement withsimilar openings 105 in the outer face of the chuck. Positioned in theseopenings 104 and105 are exteriorly threaded shafts 106 bearing betweenthe flange 103 and the outer wall of the chuck, nuts 107 the exteriorfaces of which are formed with beveled gear teeth; Secured to the outerwall of the chuck by means of screws 108 is an annular flange or ring109 extending inwardly from the outer wall of the cup-shaped member ashort distance. Mounted in the space inclosed by the ring 109 is a disk110 provided with a central opening 111 and with a plurality of openings112 disposed in a circle concentric with the opening 111. The outer edgeof the disk 110 is provided with a shoulder to receive the ring 109 forpositioning and holding the disk in place. The inner face of the disk isprovlded with gear teeth adapted to inter-mesh with the teeth on thenuts 107. Mounted in the flange 103 are keys 113 arranged to enterkey;ways 11 1 cut longitudinally of the shafts 106 for locking themagainst rotation in unison with the nuts 107. The outer ends of theshafts 106 are preferably beveled to form a sharp edge for ing atintervals V-shaped slots 117 to receive the outer ends of shafts 106.

While I have described the mechanism for driving and supporting thering-core in detail, so that its exact construction may be understood,it will be seen that in its essence I employ a slow-speed mechanism, inthis case represented by the clutch member 73, and a fast-speedmechanism, here represented by the clutch member 72, and aspeed-cl1anging mechanism, here represented by the clutch member 71 andits shifting lever 86. But when I use the terms fastspeed mechanism,slow-speed mechanism and speed-changing mechanism in the claims, it isunderstood I mean any class of mechanism accomplishingthese functionsand not merely the specific mechanism herein shown. Power is thustransmitted from the shafts 50, 53, 58 (Fig. 5) to the shaft 70 (Fig.4), and in turn to the shaft 90 which, by means of a suitable chuck,carries the ring-core. To mount the ring-core on the chuck, the shiftinglever S6 is placed in its intermediate position with the clutch member71 out of contact with either the fastor slow-speed mechanism. Thelocking-stem 100 is now permitted to come into engagement with thelocking-disk 93 to hold the shaft 90, which carries the chuck, in animmovable position. This permits the ring-core to be readily placed onthe chuck. Thereupon the locking-stem 100 is withdrawn from engagementwith the lockingdisk 93 and the speed-shifting lever 86 is operated tothrow the slowspeed mechanism into action. The ring-core is now rotatedat a slow speed. At this time a single layer of rubber-coated fabric isdrawn onto the ring-core from the stock-roll. The shifting-lever is nowquickly actuated to stop rotation of the core. Thereupon a pair ofscissors in the hand of the operator separates the strip ofrubber-coated canvas, which is around ,the core, from the canvas woundon the stocloroll. The speed-changing mechanism is now again actuated tobring the fast-speed mechanism into action.

Thereupon the tread-forming and spinningrolls are brought into play. Thesupports for these I now proceed to describe.

Slidably mounted on the base 1, substantially below the positionoccupied by the chuck just described, is a housing 118 comprising ahollow metallic box having outlines approximately concentric with theshaft 90 provided with a depending lug 119 in its lower portion throughwhich extends a screw 120, manipulated by a hand-wheel 121 for shiftingthe housing 118 toward and away from the ring-core 115, therebymaklerator to gradually bring the proper amount eaneica.

in the side of the housing,118-immediately below the carriage 123 is apivoted'arm'125 provided with a pin 126 adapted to enter a hole 127 inthe side of the housing 118. Depending from the side of the carriage 123is a lug 128 provided with a pin 129 threaded to permit its adjustmentinthe lug 128.

' When the arm 125 is swung upwardly so m is here directed to Fig. 9.

that the pin 126 is positioned in the hole 127 the pin 129 will engagethe arm 125 and arrest further inward motion of the carriage therebyconstituting an adjustable stop for accurately limiting the movement Fof the carriage with respect to the core. The

carriage 123 bears an upwardly extending centrally-placed pin 130 onwhich is mount.

ed a revoluble head or turret 1-31 held from displacement by a nut 132.Reference The turret 131 bears a lock 133 exactly similar to the lockshown in Fig. 8, provided with a verticallyshiltable stem the lower endof which isadapted to enter suit-able openings 13%- in the upper face ofthe carriage 123 and lock ipivoting them at the turret in determinatepositions.

The revolving head or turret 131, which is shown simply as a sample ofone type of transversely movable support 1 may employ bears what forlack of a more suitable name It call the tread-forming-roll 14-1, thespinning-rolls 1 17-, the cutters 149 and the bead-attaching roll 156,which can be alternately brought into play because of the ro tary ortransverse movement or the head i 131 with respect to the ring-core.These inhape it to the core. In case. 01 the spine strumentalities maybe juxtaposed to the rlng-core, one after the other, by rotating thehead, Sincethe supporting head 131 is radially movable with reference tothe ring'core by means of the. hand-wheel 12a, it follows that eachofthe instrumentalities mounted thereon is radially movablewith. respectto the ring-core. in the case of the tread-ltoraning-roll 141, thispermits the opofpressure-to .bear on the canvas either which lieseunderor which astually forms the tire treadv to thoroughly smooth it andningrolls 147. the. radially movable. and in this caseslidingtsupportpermits the opera or-toypass' the rolls graduallyovergthe surface of the side. of "the fring core that "i vradially withrespect to the ring-core cilmm:

In abroader aspect "of my invention, however, I may employ mechanicalinstrumentalities, not the hands of the operator, other than sprin s orweights for pressing the spinning-r0 ls laterally against the ring-core.I shall, then, use the term power-pressed to cover generally not onlysprings and weights but other mechanical instrumentalities for pressinthe ipinning-rolls against the ring-core. en

refer to my spinningrolls as laterally yielding and no more, I mean toinclude any source of power for pressing the spinning rolls against thering-core, even the comparatively inefficient and irregular powercontained in the hands of the operator. While I have shown thesespinning-rolls as diskshaped throughout, it will naturally be understoodthat the disk-like or narrow character of the rolls is onl essential atthe periphthe spinnin -rolls.with their plane not at a right an'g e tobut to recede at an acute angle from the plane of the ring-core. Thefact is when the ring-core is rotating at high-speed, the centrifugalforce tends to throw the fabric out at a right angle from the core-planeand unless the roller recedes in the manner shown, the fabric willbecome entangled with it. Besides the spinningrolls, when mounted inthis way, are found ric.

The action of the pivoted cutters 149;will be understood without -muchdescription.

They are brought into position by turning the head 131 and forcedtogether at the proper time to trim the edges of the fabric Thebead-applying rolls 156, 158 are mounted on the arms 155 which swing onthe arms 154. v The ordinary bead, such as is used in forming a clenchertire, 'bein put into place on one or more layers of abric which havealready been applied to the ringcore, the rolls 15.6, 158 are swung intoplace and press the bead firmly into position as the ring-core rotates.i

, I have shown in Fig. 9 the type of ringcore which will be used forclencher tires. But, clearly, my machine can also be used to maketire-shoes of the inextensible-edge type. To this end I use acollapsible ringto have a better forming action on the fabcore, theshape of which in cross-section is by a knife in the hands of theworkman,

since the edge of the lateral groove will act as a guide and that thebead-applying rolls 156, 158 are dispensed with. The treadforming-rolls141 and the spinning-rolls 147 are alone used.

Before describing the operation of the device, attention is directed tothe fact that the machine is so constructed that there are two cores onwhich separate workmen can simultaneously work and place fabric, thesebeing placed diametrically opposite to each other, as shown in Fig. 1,and each core is provided with its appropriate mechanism all driven fromthe same source of power.

'The operation of my machine will now be reasonably clear. As I havebefore explained, a ring-core supplied with some adhesive material onits exterior portion is placed upon the chuck while the speed-shiftlnglever is in position to hold the speedfnechanism out of action.Thereupon, by properly rotating and locking the rotary support for thestock-rollers, a given stockroll is brought opposite to the ring-coreand the end of the fabric thereon 'is pasted against the'ring-core. Theslow-speed mechanism bein now brought into action, the ringcore slowlyrotates, making a single ;t 11rn in about ten seconds, drawing therubber-coatedfabricfrom off the stock-roll and around the tension andstretching-rolls. It results that one round of fabric 1s nowappliediunder uniform tension to the ringcore, Thereupon the speed gearis put out .of action, the ring-core stops moving, and

In this the operator cuts the rubber-coated fabric 1 across to separatethe round of fabric which is on the ring-core fromthe fabric which yetremains on the stock-roll.

The fast-speed mechanism is now brought into play. Thetread-forming-roll 141 is then brought into action to shape and smooththe tread ortion of the fabric a ainst the outer perlphery ofthe-ring-corc. T 1e. proper pressure is applied to the treadforming-rollP11 by the devices which make it radially movable, that is by thehandwheel 124 which radially moves the carriage 121 and 131. The partsof the tire which will ultimately lie under the tread having the treadportion of the tire-shoe. are gradually moved radially by the opersenatebeen shaped] and the fast-speed gears still being kept in action, thecarriage 131 is rotated to juxtapose the spring pressed spinning-roll147 to the ring-core. The operator forces these rolls apart against theaction of the springs. At first the spinningrolls are positioned to actupon the edges t But they ator by operating the hand-Wheel 124 so thatthey pass over the side portions of the tire-shoe as illustrated inFigs. 12 12 and Fig. 9. Thus the entire tire-shoe is gradually shaped tothe ring-core. The operator now forces the spinning-rolls apart andoperates the Wheel 124 in the reverse direction to Withdraw them fromreach or the cling-core but Without touching the fabric in this reversemotion.

A single layer of canvas having been applied to and smoothed and shapedupon the ring-core, it Will be obvious that the operator will bring theslow-speed mechanism into ac tion, that he will now take hisrubber-coated fabric from a second stock-roll and will apply this uponthe layer of fabric already on the rin -core in precisely the same wayas the first layer of fabric was applied to the ring-core itself. But,by the provision of the tWo stock-rolls having the rubber-coated canvasthereon constituted of strips cut on the bias, it Will be plain that itWill be easy to arrange matters so as to have the threads of the canvaslayer first applied at an angle to the threads of the canvas'layer netapplied. This is necessary to make the best type oftire. 'llwoor morelayers of canvas having been applied, the cutter may be brought intoaction to trim the edges of the tire. Thereupon the head is put in placeand the bead-applying rolls are brought into action. Finally, severalmore layers of fabric with their threads crossed are applied to thering-core, precisely as in the case of the layers originally applied.

I may say in conclusion that whereas an operator can make seven or eighttires a day by hand, he can make from forty to sixty a day by my machineand make them better than they can be nlade by hand.
